Details of the b1558 OBD Code
B1558 code indicates a problem with the driver’s seatbelt tension sensor circuit.
OBD code B1558 means Wiper Park Sense Input Short to Battery.
This code is triggered by the Body Control Module (BCM) when it detects a short to battery in the wiper park sense input circuit.
The wiper park sense input circuit is responsible for providing feedback to the BCM about the position of the wipers, particularly when they are in the park position.
When a short to battery is detected in this circuit, the BCM sets code B1558 to indicate the issue.
Mechanic’s Tech Notes
Code B1558 indicates a problem with the driver’s seatbelt pretensioner circuit.
OBDII code B1558 indicates an issue with the automatic transmission control module (TCM) power supply.
To diagnose, use a multimeter to check TCM power and ground connections for proper voltage levels.
Utilize a scan tool to confirm TCM communication over the Controller Area Network (CAN) bus.
Visually inspect wiring harnesses and connectors for damage, and ensure connector pins are not broken, bent, or corroded.
If necessary, consider reprogramming the TCM.
